The square root of 2, or the one-half power of 2, written in mathematics as {\displaystyle {\sqrt {2}}}{\sqrt {2}} or {\displaystyle 2^{1/2}}2^{{1/2}}, is the positive algebraic number that, when multiplied by itself, equals the number 2.[1] Technically, it must be called the principal square root of 2, to distinguish it from the negative number with the same property.
The square root of 2 is equal to the length of the hypotenuse of an isosceles right triangle with legs of length 1.
Geometrically, the square root of 2 is the length of a diagonal across a square with sides of one unit of length;[2] this follows from the Pythagorean theorem. It was probably the first number known to be irrational.[3] The fraction
